unable to boot off sata after fc5 upgrade to fc6 dev

[LarryT]

Hi,
I have upgrade my fc5 to fc6-test1 enabling the dev repo.
This fc5 is on hda
I have an other fc on a sata sda. After i reboot, i cant boot the sata 
configured in grub of fc5/fc6-test1 :
-Does it come from grub ?
    ----> error 17 : unable to mount partition

Before i upgrade to fc6 test, i hade no problem to boot this partition.
